## Key lines

> “All this gun needs is another lever, to control the motion of the ship.” “Oh, that only makes it more fun,” Tom told me.

Tom jokes that the gun's difficulty is part of the fun, acknowledging the challenge of aiming from a moving ship.

_Highlights the complexity of the weapon and the crew's lighthearted attitude toward danger._

> “Always get him from in front,” he said. “Aim right here, where his chest makes a kind of V at the base of the neck. A 50 mm will go six or eight feet into him before it explodes, and it’ll explode among his heart and lungs and things.”

Tom instructs Walt to aim at the V-shaped area on the monster's chest for a clean kill that maximizes wax yield.

_Demonstrates the specialized knowledge required for efficient monster hunting._
